## Cost Optimization of Structures

**Author**: Hojjat Adeli

**Publisher:** John Wiley & Sons

**ISBN:** 0470867345

**Category : **Technology & Engineering

**Languages : **en

**Pages : **222

**Book Description**

While the weight of a structure constitutes a significant part of the cost, a minimum weight design is not necessarily the minimum cost design. Little attention in structural optimization has been paid to the cost optimization problem, particularly of realistic three-dimensional structures. Cost optimization is becoming a priority in all civil engineering projects, and the concept of Life-Cycle Costing is penetrating design, manufacturing and construction organizations. In this groundbreaking book the authors present novel computational models for cost optimization of large scale, realistic structures, subjected to the actual constraints of commonly used design codes. As the first book on the subject this book: Contains detailed step-by-step algorithms Focuses on novel computing techniques such as genetic algorithms, fuzzy logic, and parallel computing Covers both Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD) codes Includes realistic design examples covering large-scale, high-rise building structures Presents computational models that enable substantial cost savings in the design of structures Fully automated structural design and cost optimization is where large-scale design technology is heading, thus Cost Optimization of Structures: Fuzzy Logic, Genetic Algorithms, and Parallel Computing will be of great interest to civil and structural engineers, mechanical engineers, structural design software developers, and architectural engineers involved in the design of structures and life-cycle cost optimisation. It is also a pioneering text for graduate students and researchers working in building design and structural optimization.

## Construction Scheduling, Cost Optimization and Management

**Author**: Hojjat Adeli

**Publisher:** CRC Press

**ISBN:** 0203302230

**Category : **Architecture

**Languages : **en

**Pages : **178

**Book Description**

Construction Scheduling, Cost Optimization and Management presents a general mathematical formula for the scheduling of construction projects. Using this formula, repetitive and non-repetitive tasks, work continuity considerations, multiple-crew strategies, and the effects of varying job conditions on the performance of a crew can be modelled.L This book presents an entirely new approach to the construction scheduling problem. It provides a practical methodology which will be of great benefit to all those involved in construction scheduling and cost optimization, including construction engineers, highway engineers, transportation engineers, contractors and architects. It will also be useful for researchers, and graduates on courses in construction scheduling and planning.

## Geometric Programming for Design and Cost Optimization

**Author**: Robert Creese

**Publisher:** Springer Nature

**ISBN:** 3031793242

**Category : **Technology & Engineering

**Languages : **en

**Pages : **74

**Book Description**

Geometric programming is used for design and cost optimization and the development of generalized design relationships and cost rations for specific problems. The early pioneers of the process, Zener, Duffin, Peterson, Beightler, and Wilde, played important roles in the development of geometric programming. The theory of geometric programming is presented and 10 examples are presented and solved in detail. The examples illustrate some of the difficulties encountered in typical problems and techniques for overcoming these difficulties. The primal-dual relationships are used to illustrate how to determine the primal variables from the dual solution. These primal-dual relationships can be used to determine additional dual equations when the degrees of difficulty are positive. The goal of this work is to have readers develop more case studies to further the application of this exciting mathematical tool.

**Pages : **182

**Book Description**

Prime objective of any business is to get more PROFIT on investment. We are in the customer driven era. Producer's monopoly for sales price fixing has gone. Either we are owner of any business or employees of any organizations, our growth are linked with profitability & profitability only. If profit is there & growing, music will go on, if not then existence of all will be in question. Firefighting, resignation, demotion, demotivation and termination everything shall be started without looking at your past contributions & dedications. Business owner will be restless due to pending debts, installments and other essential expenditure. Now, the formula for profit has changed, PROFIT = Total sales revenue- Total costs We have only two options for survival & growth. Either we are able to make more & sell more or have to reduce our total costs. But how? Which areas we have to attack first? Are we aware about SWOT? Do we have capable & knowledgeable team? What are different cost reduction ideas? What are different methodologies to benchmark & optimize that? The objective of this small book is the same. There are many tested & trusted ideas developed by author for Big/ Medium/ Small/New startup/CEO/COO/ Plant heads/ Departmental heads/ Managers/ Engineers/ supervisors/ Talented workmen in this book under separate categories. After implementation of these ideas, any company can drastically improve their balance sheets. Even one good idea's implementation can saves some lakhs/ crores of rupees for your future regular growth & breakthrough improvements.
